Panama disease is one of the most destructive plant diseases of modern times. [2] [3] It is believed to have originated in Southeast Asia [4] and was first reported in Australia in 1876. [5] The disease didn't attract widespread attention until the early 20th century when it began heavily affecting banana cultivations in Panama and Costa Rica. [6]
Inbreeding also helps to ascertain the type of gene action affecting a trait. Inbreeding is also used to reveal deleterious recessive alleles, which can then be eliminated through assortative breeding or through culling. In plant breeding, inbred lines are used as stocks for the creation of hybrid lines to make use of the effects of heterosis.
This category includes economically significant plant diseases and the organisms that cause them including, fungi, bacteria, protists and viruses. For more information on plant pathology see phytopathology. For insects that transmit plant pathogens see Insect vectors of plant pathogens.
Crown gall disease caused by Agrobacterium. Most bacteria associated with plants are saprotrophic and do no harm to the plant itself. However, a small number, around 100 known species, cause disease, especially in subtropical and tropical regions of the world. [15] [page needed] Most plant pathogenic bacteria are bacilli.
Plant disease triangle. Epidemiology is the study of factors affecting the outbreak and spread of infectious diseases. [10] A disease triangle describes the basic factors required for plant diseases. These are the host plant, the pathogen, and the environment. Any one of these can be modified to control a disease. [11]
Most of the gene defects are autosomal recessives, so that if both the mother and father carry the same defect, the chance that their child will have the associated disease is 1 in 4. The molecular genetics of many of these diseases have been determined, enabling genetic testing , prenatal testing , and counseling.
Cassava plant with the typical symptoms of CBSD. Cassava brown streak virus disease (CBSD) is a damaging disease of cassava plants, and is especially troublesome in East Africa. [1] It was first identified in 1936 in Tanzania, and has spread to other coastal areas of East Africa, from Kenya to Mozambique.
